ok i just put a new amp to my L5 and the amp will cut out due to lack of power and my headlights dim really bad. the worst i have ever seen an amp and sub do. if i were to put a 2 farad cap would that solve my problem or do i need to go the route of a red top optima battery and get my alternator worked to produce more than the factory 80 amps.

damn, i'm not an audio/electrical guy, but that sound like you're drawing a shit ton of power. maybe the 130 amp alternator that you get with the tow package would help? i'm sure a better battery wouldn't hurt either. how old is the battery?

like i said, i'm not expert, so i hope someone else chimes in. good luck bud

You can get a 2 Farad - 5 Farad on ebay relatively cheap. I would think that should do the trick, but it depends what other accessories you are running. Maybe install the Yellow Top or Die Hard Platinum.

4 gauge or larger wire, better battery, and h/o alt first then cap .. cap would be the last thing i would do .. for real take it from me have been doing car audio for 15 years..

Why spend all the money on everything you listed when you could get a Cap which is the 2nd cheapest fix on the list? Fill the cap and neither the alternator or battery will be working as hard at such a constant rate.

I know when I blew my alternator and battery, I replaced the alt. with an OEM one and an Optima Yellow top battery. Then added a 1 F cap, zero problems after that. I would think if OP added a decent sized Cap and maybe a new battery he would be fine.
